tap thread not long enough for 40mm w/top

[jacobleslie]

Ive bought a tap for my kitchen, the thread isn't long enough for tap tails after fitting backing nut as shown and there isn't enough space to fit extension. Picture also shows rubber washer removed which didn't help at all, any help would be appreciated.

You need a 1/2 inch female x 1/2 inch male fitting. That will take the place of your nut and allow you to connect your tails.
You may need a washer or two that will act as a spacer or that fitting might tighten up against the worktop.

Use a holesaw slightly larger than the nut to create a rebate for the nut to sit in. shouldn't need to go deeper than 10-15mm. You'll need a box spanner for the nut but these are available from plumbers merchants for not much money.

Is it possible to buy a tap thread extension if it's removable?

You could cut the backing nut down ?.

Yes..I was thinking about cutting the nut in half and make a bigger hole underneath and that should do it ?
